Post as a guest Name. Todor Simeonov 1, 3 The behaviour of the diode voltage limiter is similar to this circuit: The second will work with minimal distortion only with highest impedance inputs – about 1 MegaOhm, while the first can work with kOhm loads without an issue.

Link to the datasheet. The first makes voltage limiting on the low power circuit of the OpAmp and then the ouput emitter follower as its name says outputs a voltage with similar waveform but with higher load capability.

DimitriPetrucci see the update. The result will be some kind of oscillator, but it is uncommon. Without a datasheet, this is a non-question.
Open the datasheet from your link on page 16 and look where pin 8 comes from.
I’m trying to understand what’s the purpose of the two diodes connected to the compensation pin 8and what the output of the comparator is supposed to be. Would it still work like a comparator? The behaviour of the diode voltage limiter is similar to this circuit:.
See how the signal is cut. But, what if I put a capacitor in the positive feedback?
Email Required, but never shown. In your second schematic the output of the OpAmp will be like the first waveform, but because of the resitor divider will be scaled and moved up so its minimum is about 0V and its maximum is about 5.

The difference will apper when you close the feedback loop for some exact gain. Sign up using Email and Password.
Similar thing is done on Fig. I updated the post with a modified schematic, that way would be equivalent? LM comparator and diodes on compensation Dataxheet Question.
Update The second schematic is not equal to the first.
